In poker, the royal flush stands as the most powerful and coveted hand that can defeat any opponent. Known for its extreme rarity, this hand is the dream of every poker player. Getting a royal flush is so rare that it becomes a defining milestone for those fortunate enough to see it firsthand.
For poker enthusiasts, hitting a royal flush is more than just a win; it’s a bucket-list moment. This guide dives into its significance, structure, and why it’s regarded as the ultimate hand in a poker game.
In poker, one hand sits at the top of the rankings—the royal straight flush. It’s the strongest, rarest, and most iconic hand you can get, and if you’re lucky enough to hit it, no other standard hand can beat you.
A royal straight flush is made up of five specific cards: 10, Jack, Queen, King, and Ace, all in the same suit. That means all five cards must be hearts, diamonds, clubs, or spades—no mixing suits allowed. For example, if you have 10♠ J♠ Q♠ K♠ A♠, that’s a royal flush in spades. However, if just one of those cards is a different suit, it doesn’t count.
The term ‘royal flush’ might be familiar to you since that’s the most common name used in English-speaking countries. However, in Japan, it's often referred to as a ‘royal straight flush’—a slightly longer version of the same thing.
You might wonder why it's so strong versus the other, so here’s a quick explanation. A straight flush is also five cards in a row from the same suit, but it can start at any number. For example, 6♦ 7♦ 8♦ 9♦ 10♦ is a straight flush—but it’s not royal. Only the 10 through Ace combo counts as a royal straight flush.
Here’s a table for better understanding:
| Royal straight flush | Straight flush |
| A specific type of Straight Flush made up of 10, J, Q, K, A, all in the same suit | Any five cards in a row, all in the same suit, but not necessarily 10 through Ace. |
| The highest possible hand in standard poker, nothing can beat it. | Second-highest hand in poker, next to the royal flush. |
| Example: ♠️ 10♠ J♠ Q♠ K♠ A♠ | Example: ♠️ 6♠ 7♠ 8♠ 9♠ 10♠ |
| Only four possible combinations. One for each suit. | Still rare, but much more common than a royal flush, as there are many possible combinations. |
Building a royal flush isn’t about skill alone—it’s mostly about luck, but knowing what to look for can help you spot the opportunity when it comes. Here’s how:
To form a casino royal straight flush, you need five specific cards: 10, Jack (J), Queen (Q), King (K), and Ace (A)—and all must be in the same suit. This can be hearts, diamonds, clubs, or spades, but they cannot be mixed. If even one card is a different suit, it’s no longer a royal flush.
For example:
♠️ 10♠ J♠ Q♠ K♠ A♠ = ✔ royal flush in Spades
♥️ 10♥ J♥ Q♥ K♥ A♥ = ✔ royal flush in Hearts.
Each suit only has one royal flush combination, so there are only four possible royal flush hands in a standard deck.
It’s easy to confuse this with other strong hands, but remember: the order (10 to A) and the matching suit make it a royal flush.
If the criteria above were not met, it is safe to assume that your combination is incorrect. For example:
At first glance, it might look like a royal flush. The card values are correct: 10, J, Q, K, A. But if you look closely, the ace, queen, and 10 are a diamond (♦) while the rest are spades (♠). That means the suits don’t match, so this hand is not a royal flush.
In this case, it’s not even a Straight Flush—because it also requires five cards in the same suit. You have a straight (10 to A), but the mixed suits disqualify it from anything higher.
At a glance, it looks strong—and it is! All the cards are in the same suit (hearts) and in a sequence. It might be confusing, but here’s the problem: the hand starts with 10, and doesn’t include the Ace. That means this is a straight flush, not a royal flush.
A royal flush only happens when the five cards are: 10, J, Q, K, A of the same suit. Any other combination—no matter how close—is not royal.
In poker, all hands are ranked from weakest to strongest, with the royal flush as the best possible one. If you land it, no one can beat you.
Here’s a quick look at the standard poker hand rankings, from strongest to weakest:
| Rank | Poker Hand | Description |
| 1 | Royal straight flush | 10, J, Q, K, A of the same suit |
| 2 | Straight Flush | Any five cards in a row, same suit (e.g. 5♣–6♣–7♣–8♣–9♣) |
| 3 | Four of a Kind | Four cards of the same rank (e.g. 9♠–9♦–9♥–9♣) |
| 4 | Full House | Three of a kind + one pair (e.g. K♠–K♣–K♦–6♥–6♣) |
| 5 | Flush | Any five cards of the same suit, not in order |
| 6 | Straight | Five cards in a row, different suits |
| 7 | Three of a Kind | Three cards of the same rank |
| 8 | Two Pair | Two sets of matching cards (e.g. 8♣–8♦ and 5♠–5♥) |
| 9 | One Pair | One set of matching cards |
| 10 | High Card | None of the above—the highest card wins |
In Texas Hold’em and other games with community cards, it's possible (though extremely rare) for two or more players to complete a royal flush using the same five cards from the table.
Here’s what happens:
So, even if both players hit the dream hand, no one wins outright.
Under standard rules, a royal flush can’t be beaten. However, in some poker variants that use wild cards or jokers, one hand is stronger than royal straight flush: Five of a Kind.
So, while a royal flush is unbeatable in standard poker, keep in mind that house rules and wild cards can change everything.
Out of the millions of possible card combinations, the royal flush appears only a tiny fraction of the time. That rarity makes it so valuable and exciting when it happens.
In standard 5-card poker, the probability of being dealt a royal flush is approximately 0.00015% (or about 1 in 649,740 hands). To give you a perspective, here are the poker hands, including the royal straight flush probability:

The probability of landing a royal straight flush isn’t the same across all poker games. It depends on the number of cards dealt and how the game is structured. Here’s a quick look:
Looking to try your luck at a royal straight flush? Here are some of the best poker variants you can play at Bitcasino:
This is the most popular poker variant in the world. With seven cards, the chances of completing a royal flush are higher than in classic five-card games, but still extremely rare.
In Omaha, players receive four hole cards, but must use two from their hand and three from the board to form their hand. This structure creates more possibilities for big combinations, giving a slightly better shot at a royal flush than Texas Hold’em.
This is a five-card stud poker game where you play against the dealer. You get all five cards at once, so the odds of hitting a royal flush are similar to traditional stud.
If you’re trying to up your chances of hitting that extra rare hand, these three variants are your best bet. Despite the higher percentage of getting a royal flush, it’s still rare and would take a long time (or extreme luck) to build.
Landing a royal flush is every poker player’s dream, but it’s vital to approach it with realistic expectations. Because the odds are so tiny, chasing this winning hand should never be your primary goal. Instead, focus on smart strategies that keep you in the game longer and might incidentally increase your chances of seeing this rare hand. Here are some tips to help you:
Each card in the deck is not just a tool; it’s your friend. To build a poker royal flush, you need a specific set of cards; to do this, you must understand each card in the deck. If you’re currently holding high cards (king, queen, jack), note that you’re only a few cards away from a royal flush, so it's best to hold on to them.
Once cards are dealt, don’t forget that your hand is not final. Depending on the variant, you can ask for more cards if you think you can build it. If your hand seems reasonable, go for it, as it might be the best option to complete that royal flush.
A poker royal flush has a probability of 1 in 649,740 to land in your hand. That means that it's an extremely rare occurrence that most poker players won’t experience in their lifetime.
If you actively chase it, you’ll go bankrupt quickly and might be discouraged from playing poker again. Instead, be better at playing poker and practice playing each hand, so you can take their advantages and put them to use when the situation requires them.
If you’re trying to get a royal straight flush, here are some important points every poker player should keep in mind:
While it is the most satisfying to build, the royal flush is still the rarest poker hand, which only comes in 1 in 649,740.
Some poker games incorporate jokers and wild cards into the deck. This means that a royal flush is not the highest hand in that variant.
While trying to get a royal flush is a valid goal, don’t play mainly to get it. Building your strategy around the rarest hand will leave you disappointed and defeated in most games.
If you want to experience a royal flush, be as consistent as possible. As with the tip above, don’t play to experience it; play to enjoy it. In time, the ultimate hand will land in your hands.
